Featured Reviews

Tolu Omolaja - PeerSpot reviewer
Great URL scanning and attachment scanning, but I would like more proactive threat analysis
The two main features that prove most beneficial for us are URL scanning and attachment scanning. URL scanning involves an automatic scan of links and emails. When a user clicks on a link within an email, the system promptly checks the link's safety. If the link is deemed safe, access is granted automatically. However, if it is flagged as unsafe, we receive feedback and notification to caution us about the potentially harmful link. At this point, we are presented with the option to proceed or return. I have personally witnessed the system identify a few unsafe links, making this the primary advantage of using the solution. The second crucial aspect is the scanning of attachments. When an email containing an attachment arrives, we receive a notification of the new email, along with information that the attachment is being scanned for threats. This additional layer of security provides peace of mind for our organization. While Microsoft Defender for Office 365 offers numerous features, these two stand out as particularly impressive and valuable to us.
Vignesh  K - PeerSpot reviewer
Auto scanning and enhanced security but re-adding protections need improvement
At that time, we observed certain issues with the product. The functionalities could be improved, such as the isolation feature. If we remove our protection, we cannot easily add it back. If, in our organization, we need to remove a specific system for a particular time, we cannot add it back for security after doing so. This is one thing we have experienced. Scalability is also lacking. If we want to do the same thing repeatedly, there's not much the solution offers; it isn't very strong.
Steve Bowtell - PeerSpot reviewer
Exceptionally easy to integrate and covers a multitude of cybersecurity issues
The solution's interface appears very simple, but it is very complicated in the back end. So, it removes all the complications that an MSP or an MSSP would normally have. The solution's maintenance depends on whether you run it like an MDR platform where you provide the detection response part for the customer. That would normally be the MSP part. Sometimes, you have customers who are just happy to get an email and tell them what the problem is, and they fix it themselves. If there's no in-house expertise, the MSP or the MSSP can do the maintenance. If there's in-house expertise, it's just a matter of advising them. Overall, I rate the solution an eight out of ten.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The auto-scanning feature is quite beneficial."
"The auto-scanning feature is quite beneficial."
"The solution is exceptionally easy to integrate and covers a multitude of cybersecurity issues."
 

Cons

"Microsoft Defender for Office 365 should improve the troubleshooting tools. It's unclear whether the device is blocked at the firewall level or at the device itself. The granularity needed for troubleshooting is currently lacking. From my perspective, Microsoft should address this issue to benefit many users who likely share the same sentiment."
"Specifically, within Microsoft Defender for Office 365, I want it to improve the DLP capabilities."
"We still see many false positives from time to time with Microsoft Defender for Office 365, so it would be good if we can reduce those false positives and provide better workflows for our end users, as sometimes they may not know what to do when they encounter a false positive."
"Microsoft needs to broaden its global support presence by establishing teams of subject-matter experts in all regions."
"Configuring the default strategies and policies in Microsoft Defender for Cloud Apps generates a lot of noise and false positives."
"There is a different console for different things; I just want one consolidated console."
"Configuration requires going to a lot of places rather than just accessing one tab."
"Several simulation options are available within 365, and the phishing simulation could be better."
"Scalability is lacking. If we want to do the same thing repeatedly, there's not much the solution offers; it isn't very strong."
"The functionalities could be improved, such as the isolation feature."
"The solution's security awareness training and phishing are very United States-focused and don't work very well in Australia."
 

Pricing and Cost Advice

"I know that the product is incredibly expensive."
"Defender is a little bit more expensive as compared to others. We are in the manufacturing environment. So, we don't have a high budget for all of our endpoint devices. Its cost is a major concern for us."
"The product is expensive."
"For licensing, it's usually a yearly package for customers who are subscribed to Office 365, but they can also pay on a monthly basis."
"Microsoft Defender for Office 365 is an add-on to the Office license. Many customers are purchasing this solution."
"The pricing is normal. Considering its popularity, it's not overpriced."
"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
"While Microsoft Defender for Office 365 necessitates pricier E3 or E5 subscriptions, the extensive functionality offered by these licenses across various Microsoft products justifies the investment."
